Respiron strengthens and exercises the lung muscles by encouraging controlled, long, slow, deep and focused breathing which:
Simply breathe in through the mouthpiece (do not blow) to raise the three balls of the device in sequence, keeping each of them elevated for several seconds.
Please Note: breathing in must be vigorous and deep, but not quick. The balls should rise in a mild and uniform movement, rather than suddenly. If all 3 balls are too dificult, set the adjustability lever to 0 (easy) and start by raising the first ball, and work up to all 3.
